Squid

installation

https://doc.ubuntu-fr.org/squid

#sudo apt-get install squid
#sudo service squid3 start

rendre squid transparent (et obligatoire)

http://wiki.squid-cache.org/ConfigExamples/Intercept/AtSource

Editer /etc/squid3/squid.conf avec les trois lignes suivantes <licode file=/etc/squid3/squid.conf>

acl localnet src 192.168.0.0/24
http_access allow localnet
http_port 3129 intercept

</licode>

Ce qui donne le fichier de conf suivant: <licode file=/etc/squid3/squid.conf> acl localnet src 192.168.0.0/24 acl SSL_ports port 443

acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT

http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localhost manager http_access deny manager http_access deny to_localhost http_access allow localhost http_access allow localnet

http_access deny all

http_port 3129 intercept

Relancer squid

#sudo squid3 -k reconfigure

Configurer le firewall pour laisser passer les requêtes de squid vers le port 80 et rediriger les autres

#sudo iptables -t nat -A OUTPUT --match owner --uid-owner proxy -p tcp --dport 80 -j ACCEPT
#sudo iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to-ports 3129

Installer le paquet iptables-persistent pour garder en mémoire les règles du firewall
